The Muncie A20-A1015-SX51XPX or A20A1015SX51XPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is independently rotatable, giving installers flexibility in tight engine compartments. Extended-length PTO mounting fasteners and increased housing clearance simplify installation. Tapered roller bearings and an enlarged output shaft diameter are built in to extend service life under continuous-duty cycles. The unit carries a single intermittent/continuous torque rating across three available housing arrangements and is compatible with the EX Drive shaft extension.
